I believe its time to see a new GI. I had the same issues for many years until I found a good GI who put me on different medicines that helped me tremendously. You may find you have a case of pouchitis, which a round a antibiotics might help. (Leakage is my number one sign of pouchitis.)
Definitely look for a good GI. I remember too well how being sleep deprived isn't really living. I don't want you to have to continue to go through this if you can get some help.
Wishing you the best
